Can any hps fixture be used hanging verticaly or does it have to be made for that function?

Can i get a "econo" system and just ditch the wing ??:confused:
 
Any holder will be fine. some bulbs don't like to be hung vert. Not many that we have seen though.
 
im kinda confused with ur question.... depending on the shade the hps light will either hang verticallay or horizontally.....

Vertical- better for growing 1 large colas

Horizontal- better for bushy types trees with mutlple branches
 
I plan on doing my next grow vertical and I have not seen anything on specific bulbs or parts you need. I plan on just removing the shield and hanging it in the middle of a grow tent.
 
some bulbs are ment to be hung one way and some are universal.. its in the code..

U or VBU - vertical Base Up or VBD - Vertical Base Down

Burning Positions
  • VBDFilament vertical with lamp base down. VBUFilament vertical with lamp base up. HorFilament horizontal. UniversalBurns at any angle. +/-nMaximum permissible deviation of n degrees from recommended burning position.

I recently was given a bulb for free(my 400MH burnt out and i' m running my 400hps) and after doing research on the serial number MVR/STD/VBU/HO or something... I found out it was a VBU with is vertical bulb hanging down .. I have a horizontal setup with the fixture and I don't feel like altering it although I can and will when/if the HPS burns out... I also read that a Metal Vapor bulb will work in a MH fixture but not the other way around.. so I might just try it one day to see...
 
it's for safety reasons and life of the bulb.. they will obviously work in whatever position you put them in... BUT it's not as safe and the life of the bulb is hindered..
